Abstract

Energi surya memiliki banyak aplikasi dalam kehidupan manusia. Salah satunya adalah sebagai solusi energi terbarukan pada sistem hybrid antara fotovoltaik (PLTS) dan PLN untuk mengatasi masalah tersebut. Salah satu komponen penting dalam pembuatan pembangkit listrik tenaga surya adalah solar charge controller. Pada prinsipnya pengisisan muatan baterai adalah dengan cara mengaliri baterai dengan arus listrik secara terus menerus. Pengisisan dihentikan ketika beterai telah sampai tegangan maksimumnya, yaitu pada tegangan 48VDC. Jika baterai telah mencapai tegangan maksimumnya tetapi tetap dilakukan pengisian maka akan meninggalkan kerugian yaitu pemborosan energi listrik serta akan terjadi pemanasan berlebihan pada baterai yang akan memperpendek umurnya. Untuk menghindari kerugian tersebut, maka akan lebih baik jika charger dapat bekerja secara otomatis untuk mengisi baterai jika baterai itu kosong muatannya, yaitu pada tegangan 43,5V DC. Dengan demikian tegangan tidak stabil akibat beban bisa dihindari. Sistem pengendali ini menggunakan transistor IRF 4905 sebagai switch dan kontrolernya dengan mikrokontroler ATMega 8535. Berdasarkan spesifikasi charging aki, output kontroler tersebut dapat digunakan untuk charging aki 48 volt, dengan pembacaan error pada baterai sebesar 1,1% dan error pada solar cell sebesar 19% ============================================================================================ Solar energy has many applications in human life. One of them is as a renewable energy solution. Due to the cost of electrical energy is more expensive, it is necessary to design a hybrid system between photovoltaic (PLTS) and PLN to overcome the problem. One important component in the manufacture of solar power plants is the solar charge controller. In principle, charging the battery charge is by flowing the battery with an electric current continuously. The filling is stopped when the batter has reached its maximum voltage, ie at a voltage of 48VDC. If the battery has reached its maximum voltage but still done charging it will leaves a loss that is waste of electrical energy and there will be excessive heating of the battery that will shorten its life. To avoid such losses, it would be better if the charger can work automatically to charge the battery if the battery is empty charge, ie at 43.5V DC voltage. Thus the voltage is unstable due to the load can be avoided. This control system uses IRF 4905 transistor as switch and its controller with ATMega 8535 microcontroller. Based on the battery charging specification, the controller output can be used for 48 volt battery charging, with 1.1% error reading on the battery and an error in the solar cell of 19%
